HTML <head> Tag
The HTML <head> tag represents the head section of the HTML document.
The <head> element can contain other HTML tags that contain metadata. Metadata provides information about the document such as title, description, keywords etc. A typical HTML document might contain a <title> tag, one or more <meta> tags, a <script> tag, and a <style> tag - all enclosed within the <head> element.
Most metadata are not displayed in the browser (although the title usually appears in the browser's title bar) but it can be useful for the functionality of the page.
Syntax
The <head> tag is written as <head></head> with the metadata content enclosed between the start and end tags. The <head> tag is placed between the opening and closing <html> tags.
Most HTML documents must have a <title> tag within the <head> tag (the only exceptions are: if the document is an <iframe> srcdoc document or if title information is available from a higher-level protocol, for example in the case of an HTML formatted email).

Event Handlers
Event handler content attributes enable you to invoke a script from within your HTML. The script is invoked when a certain "event" occurs. Each event handler content attribute deals with a different event.

Most event handler content attributes can be used on all HTML elements, but some event handlers have specific rules around when they can be used and which elements they are applicable to.
